Abstract :
A CPLD (complex programmable logic device) based control IC for a three-phase auxiliary resonant snubber inverter (RSI) is proposed and constructed. A control scheme implemented in the control IC is based on carrier-based pulse width modulation (PWM). The IC generates gate-signals for main- and auxiliary-devices of a three-phase RSI based on the proposed control scheme. In this paper, the effectiveness of the proposed control IC was verified through experiments. As a result, ZVT (zero voltage transition) turn-on at the main devices was realized and a smooth sinusoidal output current was obtained by use of the control IC
